Kirby, &c. the antenne of which are biflabellate, the flabella on each side 
arise from the same part of the joint, and not (as in the dipterous genus 
Ctenophora) from various distances from the base of various jomts. In 
the two species of my new genus, however, the antenne have upwards of 
thirty-five joints, the first and second alone being without pectinations, 
thus pointing the way tothe genus Rhipicera, one species of which, from 
New Holland, Mr. Kirby describes as having upwards of thirty pectina- 
tions in the antenne. The genus has doubtless a near affinity with 
Phengodes, and was separated by Hoffmansegg from the Lampyrides in 
the same paper in which he established that group. The generic cha- 
racters given by him were by no means sufficiently detailed, and I have 
therefore attempted to supply the deficiency. And indeed in regarding 
the following insects as belonging to this genus, it is proper to state, that 
Illiger describes the antenne as having ‘ mehr als vierzig Gliedern.”’ 
We may presume that the female when discovered will be found to 
possess simple antenne. 
The student will find some interesting observations upon the singular 
anomaly of certain insects possessing more or less than the usual number 
of joints in the antenne, in Dalman’s Analecta Entomologica, under the 
genus Polytomus, and also in Kirby and Spence, Vol. III. 321 and 519.

The only two specimens which I have yet seen of this insect are males, 
one is in Mr. Haworth’s cabinet, and the other in my own. I had 
originally named the insect in my MSS. after that gentleman as a slight 
return for the many entomological favours which I have received from 
him, and through whose kindness my own collection has been enriched
